Skip Autumn if you're not building on Stripe, need a no-code UI, or have simple subscription billing that Stripe Billing already handles.
Stripe fees (0.7% and 2.9% + 30¢) still apply on top of Autumn's plan fees.
Autumn's free tier is generous for early PMF—8K billing volume and 10M API requests. Pro at $375/mo suits scaling teams, though it's pricier than Stripe Billing alone. For high volume, Scale is custom. Consider Orb or Metronome if you need advanced metering but they don't include entitlements.

About Autumn
Autumn is billing infrastructure for AI startups that need usage-based pricing without building their own billing stack. It sits between your application and Stripe, turning pricing logic into configuration so you can adjust plans, variants, and custom contracts quickly — the vendor claims 10x faster iteration. The system centers on a real-time credit ledger that manages grants, rollovers, expirations, sub-entity balances, spend caps, and auto top-ups. It also handles feature entitlements, both boolean and metered, and offers a minimal API with just attach, check, and track operations. Designed with agents in mind, the API is built for coding assistants and automated workflows, with CLI and MCP support included. Autumn is self-hostable as open source or available as a hosted cloud service. Recent updates show a deliberate focus on core billing reliability and agent-ready design, stepping back from multi-region complexity. Compared to Stripe Billing alone or in-house metering, Autumn adds a real-time enforcement layer without replacing your payment processor.
Behind the Verdict
Autumn fills a specific gap: real-time usage metering and entitlement enforcement on top of Stripe. If your business model involves credits, complex plans, or custom contracts, building that ledger yourself is a big time sink. Autumn's config-driven approach means you can change pricing without deploying code, which is a genuine differentiator. The recent pivot to agent-friendly APIs is forward-looking, but it's a double-edged sword. If you're not using AI coding assistants, the deprecated React hooks and shadcn components leave you with only the raw API, which is more work. The free tier supports 8K monthly billing volume and 10K customers, plenty for early-stage products. The Pro tier at $375/mo scales to 50K volume, includes usage event aggregation and data warehouse integration — good for growth-stage teams. For high-throughput needs, Scale is custom. Watch out: the move back to single-region may impact latency for globally distributed apps. Also, Stripe fees apply on top, so factor that into your costs. In practice, we'd reach for this when you're on Stripe and need credit-based billing with real-time gating, and you're comfortable with an API-first, agent-oriented workflow. It's a stronger fit for developer-led teams than for those expecting a full no-code billing UI. For simpler subscription billing, Stripe Billing alone may suffice — you don't need the ledger complexity. But if you're iterating on pricing frequently, Autumn can save months of engineering time.

Models Under the Hood
as of 2026-09-01
Limitations
- Autumn is built on top of Stripe billing, so Stripe fees (0.7% and 2.9% + 30¢) still apply.
- The hosted version is currently single-region (as of June 2026), which may impact latency for global users.
- The blog mentions deprecating React hooks and shadcn components, indicating that the no-code UI is not a focus.
